Continually improving refurbishment

One of our strengths is in our people, their knowledge, and their willingness to work together and continually improve performance.


Our people in the NPS Group office in Hull have nearly two decades' experience of working together on the refurbishment of residential tower blocks. The blocks being refurbished originally had very poor energy performance, to the extent that many residents had switched off their heating as they could not afford to run it. We had been monitoring the buildings' energy consumption, and stringent new targets were set.


We formed a core team of specialists, and they selected a supply chain that could offer the products that enabled the targets to be met. As each refurbishment was carried out, a before-and-after measured comparison showed the increase in energy performance that had been achieved. Crucially, we kept the same core team together from one project to the next. At the beginning of each subsequent project, they held a briefing workshop to examine the lessons learned from the previous refurbishments and consider how to make further improvements in performance.


Before long the team had made so much improvement in energy performance, they faced fewer and fewer possibilities for improving the building fabric. At that point they turned their attention to residents' appliances, and improved the building's energy performance by replacing them with more efficient models. When that too reached its sensible limit, they focused more closely on cost. By researching more ways of achieving the same improvements within a tighter budget, they were able to utilise the surplus to increase the project scope.


This approach of analysis, learning, and continual improvement is helping to ensure that Hull City Council meets the requirements of its Carbon Plan and forthcoming efficiency legislation.
